Bestandes- und Freilandnährstoffeinträge in Zentralsulawesi (Indonesien) Bulk-Depositionsmessungen mittels Passivsammler im Lore Lindu Nationalpark by Stefan Köhler( )

Supra-regional deposition of nutrients in tropical rainforests represents an important source of nutrients for these ecosystems. Increasing loads of anthropogenic emitted material into the sensitive nutrient cycles of tropical rainforests lead to a shift in the nutrient balance connected with a loss of richness off species. Measuring of nutrient deposition in tropical areas is mostly difficult because of a lack of infrastructure in remote areas, and in mesoscalic areas it is even impossible. Both the transport of samples to the laboratory and the determination of low-concentrated nutrients
The rhizosphere effects of Fagus sylvatica L. and Fraxinus excelsior L. saplings on greenhouse gas fluxes between soil and atmosphere by Ann-Catrin Fender( )

1 edition published in 2012 in English and held by 29 WorldCat member libraries worldwide

Tree species influence the soil through stemflow and throughfall water, leaf litter and the root system. Little is known about the effects of tree roots on the C and N dynamics of the soil and the gas exchange with the atmosphere. In the present study, the effects of European beech (Fagus sylvatica) and Common ash (Fraxinus excelsior L.) saplings, as important European broad-leaved tree species, on C and N fluxes in the soil of a species-rich temperate forest were investigated under constant climatic conditions. The main objective was to identify root-induced changes in the greenhouse gas f
Plant Diversity and hydrological relations to groundwater in the riparian zone of Cerrado in Mato Grosso (Brazil) by Taciana Ziembowicz( )

2 editions published in 2018 in English and held by 19 WorldCat member libraries worldwide

The riparian zones are essential to environmental quality, providing human society with several ecosystems services. Nonetheless, in tropical ecosystems, an intensive overexploitation of resources can hinder their resilience thresholds, compromising key ecological mechanisms that are arguably not yet fully understood. In the Brazilian Cerrado savannah, which is connected to many river basins with abundant groundwater, knowledge gaps on the relationships between hydrological parameters and plant diversity still exist. In intensively cultivated agricultural areas with remaining riparian veget
Effects of earthworms and tree species (Fagus sylvatica L., Fraxinus excelsior L.) on greenhouse trace gas fluxes in mixed deciduous broad-leaved forests by Klaus Schützenmeister( )

Despite the large number of studies and the associated knowledge gain uncertainties on the determinants of greenhouse gas fluxes from terrestrial ecosystems still exist. It is important to bridge these gaps as land use and particularly land use change as the important driver of the feedback loops between the atmosphere and the land surface. One major process is the direct emission of greenhouse gases as land use and land use change is ranking second behind burning of fossil fuels. During the past decades, global land-use and land-cover changed dramatically and thus, the biogeochemical inter
Highly resolved thermal analysis as a tool for simultaneous quantification of total carbon, organic carbon, inorganic carbon and soil organic carbon fractions in landscapes by Truong Xuan Vuong( )

2 editions published in 2015 in English and held by 19 WorldCat member libraries worldwide

To quantify and evermore qualify carbon in soils have become highly timely task in landscape ecology. However, separating soil organic carbon (SOC) into different ecologically relevant fractions is difficult. Particularly for landscape approaches needing high numbers of samples, it is necessary to find a simple, economic and suitable method that can quantify total carbon, organic carbon and inorganic carbon as well as separate SOC fractions, preferably with a single method and a single run for each sample. A thermal gradient method was modified and tested for this purpose. The objective of
Impact of plant species, N fertilization and ecosystem engineers on the structure and function of soil microbial communities by Birgit Pfeiffer( )

2 editions published between 2013 and 2014 in English and held by 17 WorldCat member libraries worldwide

Soil microbial communities are directly and indirectly influenced by a complex system of cross-interactions between different biotic and abiotic factors influencing each other, such as plant species and their respective traits, soil nutrient content, and pH. Microorganisms shape their environment, as important drivers of the C and N cycle. Within the present thesis, several studies were conducted under controlled field and laboratory conditions as well as under natural conditions to unravel the contribution of different influencing factors. The soil prokaryotic community composition of the
Analyses of hydrological and hydrochemical fluxes in selected catchments of the Cerrado and Amazon biomes by Rodolfo Luiz Bezerra Nóbrega( )

On many levels, there is a lack of understanding regarding the impacts of deforestation on water resources and soil properties in the Amazon-Cerrado ecotone, where the Amazonian agricultural frontier is mostly present. Both the large spatial extent of this region and the wide diversity of environmental conditions requires extensive field-based data collection to allow comprehensive process characterization and to improve hydrological modelling parameterization. Furthermore, the Cerrado biome, where most of the deforestation in this region has occurred, is often not integrated into the studi
Effects of insect mass outbreaks on the C and N balance in forest ecosystems by Maren Marine Grüning( )

1 edition published in 2019 in English and held by 3 WorldCat member libraries worldwide

Intensive defoliation by phytophagous insects in forests is accompanied by high amounts of organic litter deposition which affects biogeochemical processes in soil, thereby changing nutrient recycling and release as well as the soil microbial community. Besides its effects on soil, defoliation has negative impacts on tree health, thus changing the trees' metabolic processes and altering tree-soil interactions. In this thesis mass outbreaks of the nun moth (Lymantria monacha L.) and the pine-tree lappet (Dendrolimus pini L.) in two Scots pine forests (Pinus sylvestris L.) and two non-infeste
